About MARGIVIO

MARGIVIO is a set of free profit and pricing calculators for people who sell products online. This page explains what the tools do, what they leave out and how to read their results.

What is MARGIVIO?

MARGIVIO helps you see what an order really earns once the costs that sit between the price and your profit are counted: the product, shipping, packaging, marketplace and payment fees, discounts and advertising. Each calculator works on one question, such as profit per order, the price for a target margin or the ROAS you need.

The site is written in English for sellers in the United States, the United Kingdom, Canada and Australia.

MARGIVIO is independently operated by an individual. It is not presented as an incorporated company, no registered business status is claimed, and it is a free site: there is no team, support desk or paid service.

Who is it for?

Anyone who sets prices or runs ads for an online store and wants a clear, checkable calculation: sellers on marketplaces, owners of small web shops, and people learning how margins and markups work. It is not tax, legal or financial advice.

What can you calculate?

There are five calculators today:

  • E-commerce Profit CalculatorNet profit and net profit margin for one order after product cost, shipping, packaging, platform and payment fees, discounts and advertising. It also shows a target selling price, a break-even ROAS and a three-scenario comparison.
  • Selling Price CalculatorThe lowest selling price that reaches a net profit margin you choose, with the same costs and fees, and a comparison with your current price.
  • Break-even ROAS CalculatorThe return on ad spend you need to break even on one typical order, the maximum cost per order, and an optional comparison with your real ad results.
  • Markup CalculatorMarkup and gross margin from a cost and a price, or the price for a target markup or target gross margin. It uses product cost only.
  • Discount Profit CalculatorHow a discount changes profit per order, margin and total profit, and how many orders you would need to keep the same total profit.

No other calculators are available yet.

How the calculators work

Each calculator applies written formulas to the numbers you enter, and every formula is explained on the calculator's page with a worked example. Results are calculated by this site's own code. When you change a value, the result is recalculated in your browser. When you open a shared link, the server uses the values in that link to build the first version of the page; see the Privacy Policy for what that means.

Money is calculated with exact decimal arithmetic and rounded only when shown. Choosing a currency (USD, GBP, CAD or AUD) changes the symbol only. No exchange rates are applied.

What costs are included or excluded

Included, where the calculator has a field for it:

  • Product cost, the shipping you pay and packaging
  • Shipping charged to the customer (counted as revenue)
  • Platform and payment fees, as a percentage and as a fixed amount per order
  • Discounts, which reduce the price before fees are calculated
  • Advertising, per order or as a share of revenue, depending on the calculator
  • Additional per-order costs you add yourself

Excluded everywhere:

  • Sales tax, VAT and GST. All amounts are entered and shown without tax.
  • Income tax or corporation tax
  • Currency conversion and international card fees
  • Refunds, returns and chargebacks, unless you add them as a cost
  • Storage fees and fixed overheads such as software, rent and salaries

The Markup Calculator is narrower: it uses product cost only, so it shows gross margin, not net profit margin. The other calculators include the costs listed above.

Why results are estimates

A calculator only knows what you tell it. The fee rates and costs filled in when a page opens are examples so that a result appears straight away. They are not the fees of any marketplace or payment provider, and real fees change and differ between accounts and categories. Replace the examples with your own numbers and check them against your platform's current terms before you rely on a result.

How to interpret margin, markup, ROAS and discount impact

  • Gross margin vs net profit margin. Gross margin subtracts only the product cost. Net profit margin also subtracts shipping, packaging, fees, advertising and other costs, so it is lower.
  • Markup vs margin. Markup is profit as a share of cost; margin is profit as a share of the selling price. A 50% markup is a 33.33% margin, and a 50% margin is a 100% markup.
  • Revenue vs profit. Revenue is what the customer pays. Profit is what is left after costs.
  • ROAS vs profit. ROAS is revenue divided by ad spend. It is not profit, and 1.0x is not break-even once costs and fees are counted.
  • Discount percentage vs profit reduction. A 10% discount can remove far more than 10% of your profit, because costs do not fall with the price.
  • Percent change vs percentage points. A margin that falls from 40% to 33.33% has dropped 6.67 percentage points, which is a different figure from the percent change in profit.

Limitations and assumptions

  • Amounts exclude tax, and results are not tax, legal, accounting or financial advice.
  • Each calculation models one typical order. Real orders vary in price, cost and fees.
  • The calculators do not predict demand. For example, the Discount Profit Calculator shows how many orders would keep your profit the same, not whether a discount will bring them.
  • Comparisons with real ad results assume your ad-attributed orders look like the order you entered.
  • Results depend entirely on the values you enter, and a mistake in an input gives a wrong result.
